Are we talking about the famed U.S. Navy tables?
They have a great track record, don't they?  Again,
this is just poor marketing Trey. The U.S. Navy
tables exceed this requirement of yours, yet have poor
reception in diving circles, apparently they have
poor statistics from a DCS incidence rate. Being
extensively tested is one thing. You don't happen
to have a URL for the statistics kept by WKPP, do you?

Congratulations, we've also got a doppler, that was easy.
Fortunately, I don't claim to have such vast experience.
I am concerned with what I practice though, and with
what others have to share. In the end, what I, and most
other divers are left with in the real world are some theoretical
models, and pieces of software that assist us in planning
dives, fexibility really is an asset.  Your claim to having
empirical data on decompression really doesn't help
anybody out here. This is just like all those custom tables
used by the oil industry, practically useless to the
decompression diver. "Darn, I don't have the Shell oil
deco schedule, I just have the Chevron."

When the WKPP, or it's proponents, come up here
and put there stuff up for public display, and tell
folks they should be doing this way, or that way,
it doesn't come as a complete surprise that things
are going to be inspected in detail.

The whole issue of breaks has never been dealt with.
It's another oversight in the model. Yes, the model is
one thing, and so on. But ask the decompression diver,
whether or not he is diving as per the WKPP method
and if he is using any empirical data from the WKPP, and
the answer, will likely be: No.

Funny, I seem to believe that many possible scenarios
work. Your camp seems to think only one scenario works.
I'm sure you folks are more reasonable than this.

Fine, I'll join the list.

But tell us Trey, the major reason for the 50/100 decompression
regime is for logistical reasons, isn't it? Cost, time, effort, and
consistency of results.
